我试图创建一个自定义的分析器的索引,使令牌和生成使用此自定义索引。
我试着做了以下几件事

PUT /index_name/_settings
{
  "analysis" : {
    "analyzer":{
      "custom_analyzer_name": {
          "type": "custom", 
          "tokenizer": "standard",
          "char_filter": [
            "html_strip"
          ],
          "filter": [
            "lowercase",
            "stop"
          ]
        }
    }
  }
}

这给了我这个错误

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Can't update non dynamic settings [[index.analysis.analyzer.custom_analyzer_name.char_filter, index.analysis.analyzer.custom_analyzer_name.filter, index.analysis.analyzer.custom_analyzer_name.type, index.analysis.analyzer.custom_analyzer_name.tokenizer]] for open indices [[index_name/Zd4fisCyR6alpkzj-6uSgQ]]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Can't update non dynamic settings [[index.analysis.analyzer.custom_analyzer_name.char_filter, index.analysis.analyzer.custom_analyzer_name.filter, index.analysis.analyzer.custom_analyzer_name.type, index.analysis.analyzer.custom_analyzer_name.tokenizer]] for open indices [[index_name/Zd4fisCyR6alpkzj-6uSgQ]]"
  },
  "status": 400
}

我也试着这样创建分析器

PUT /index_name
{
  "settings": {
    "analysis": {
      "analyzer": {
        "custom_analyzer_name": {
          "type": "custom", 
          "tokenizer": "standard",
          "char_filter": [
            "html_strip"
          ],
          "filter": [
            "lowercase",
            "stop"
          ]
        }
      }
    }
  }
}

但这给了我以下错误

{
  "error": {
    "root_cause": [
      {
        "type": "resource_already_exists_exception",
        "reason": "index [index_name/Zd4fisCyR6alpkzj-6uSgQ] already exists",
        "index_uuid": "Zd4fisCyR6alpkzj-6uSgQ",
        "index": "index_name"
      }
    ],
    "type": "resource_already_exists_exception",
    "reason": "index [index_name/Zd4fisCyR6alpkzj-6uSgQ] already exists",
    "index_uuid": "Zd4fisCyR6alpkzj-6uSgQ",
    "index": "index_name"
  },
  "status": 400
}

如何在Elasticsearch索引中正确创建和分配自定义分析器?

从您得到的错误判断,index_name已经存在,因此除非先删除它,否则无法重新创建它。
如果您无法删除它,但只想修改分析器,则可以先关闭索引,然后重新打开它:

POST index_name/_close

PUT /index_name/_settings
{
  "analysis" : {
    "analyzer":{
      "custom_analyzer_name": {
          "type": "custom", 
          "tokenizer": "standard",
          "char_filter": [
            "html_strip"
          ],
          "filter": [
            "lowercase",
            "stop"
          ]
        }
    }
  }
}

POST index_name/_open
